Application filed September 3, 1902. herial Trio. 391,181.

To all whom it may concern:

Be it known that I, Jenn G. @rvrnan, a citizen of the United States, residing at Al toona, in the county of Blair and State of Pennsylvania, have invented certain new way-Ties, of which the following is a specife cation.

The invention relates to metallic railwayt'ies oil. that description in. which the body of the tie comprises a hollow shell or casing inclosing a resilient filling. it also relates to clamping; mechanism for securing the rail to the tie.

lt consists in the novel construction, combination and arrangement of parts, such as will be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings.

In the accompanying drawings, in which similar reference characters designate corresponding parts, Figure 1 is a perspective View showing an end of the tie with the clamping; mechanism. Fig. 2 is a longitudir al sectional view. Fig. 3 is a detail per a similar view of one end of the clamp;

The tie comprises a casing of sheet metal in the general sha e and dimensions of the ordinary wooden tie. It has the flat upper surface or crown l, the sides 2 extending, dovl wardly at right angles from the crown, and the flanges 3 bent inwardly from the lower edges ol? the sides. In the sides inetal is-bent to form the opposing ribs extending longitudinally of the tie. These ribs, which have considerable depth, form springs to give the tie the required resiliency to inset the traillc conditions of the road.

In the casing is the elastic filling 5 of such a nature to give the tie the stability required and which, at the same time, will permit the tie to yield to take up the-shock of the pass ing" load. The filling is preierably composed which latter may be either mineral or vegetable. The asphalt and bitumen give the reqnired body and cohesion. to the filling and the iibcr acts as a binder to hold the mass tog The fiber also serves to render the nco within the tie a i ribs -l. its there a "'ltl opening between the edges the material of road-bel can in the tie and adhere to the same over a considerable space. This union of the roadbed material and the filling of the tie holds the latter against creeping.

The rail is held in place on the tie by the clamps 6 and 7 placed on opposite sides of the rail and secured to the tie. The inside clamp 6 is shaped at its inner end to fit the base and web 0? the rail and to abut against the under side of the crown. side clamp T is shaped to fit over the edge of the base, as at thand is bent upwardly to form the brace or strut 9. The upper end oi the latter abuts against the upper part of the web and is shaped to fit the under side of the crown, as at 10. Bolts 11 pass through the web of the rail and the clamps to hold-the several parts together at that point. upper part of the clam 7 are the slots l2 throng 1 which the bo ts 11 pass. These slots permit an adjustment of the clamp on the rail.

The outer end of the clamp 7 is provided with the diagonal flange 33 that engages the slot l leirtending obliquely across the crown of the tie.

contact with the fillin The inner end of the outlo the The slot is considerably longer than the flange so that the clamp can be i moved sidewise. To the flat part of the clamp is the groove 15 extending diagonally across the same parallel with the flange 13 and with the slot M. The edges of the In assembling the parts, the bolt 19 being.

in position, the clamps 6 and '7 are placed on opposite SlCiGS OT the rail. The clamp 7.

is positioned. with its inner end abutting against the rail, the flange 13 engaging the slot i l, and the groove 15 registering with the bolt 19. The clamp then adjusted witlirelation to the rail and the bolts 11 secured by the nuts tightened on their ends. The holding plate ii 7 is then placed over the thegro'ove l5 with its serrations the serrations 16, The not is ontothe bolt 19 and the several relay secured together. The

, tfirmlyin place by the bolt,

through the engagement of its serrations with those on the edge of the groove will firmly hold the clamp against movement sidewise. The flange 13 engaging the slot 14 Will take up any end thrust of the clamp exerted by outward pressure on the rail.

As the clamp 7 is on the outside of the rail it receives the greater strain. The strut or brace 9 strengthens this clamp to Withstand the strain. As the flange of the Wheel is on the inside of the rail the strut or brace Will not be in the Way of the flange.

Having thus described my invention .What I claim and desire to secure by Letters Patent is:

1. In a metallic railway-tie, the shell or casing, a clamp on said shell or casing having a serrated groove, a bolt mounted in said shell or casing and extending through said' groove, and a serrated holding plate seated in said groove on said bolt.

2. In a metallic railway-tie, a shell or casing having a slot extending diagonally across its crown, a clamp en aging the rail at its inner end and adjustab e on said shell or casing and provided With a serrated groove parallel with said slot, a flange on the outer end of said clamp engaging With said slot, a bolt mounted in said shell or casing and extending through said groove, and a-serrated holding plate seated in said groove on said bolt.

In testimony whereof I hereunto afiix my signature in the presence of two vvitne'sses. JOHN G. SNYDER.
